I saw it happen once when I was young team lead. I had a number of people that worked on my team.

One day I was asked how many people we would need if we stopped doing one task. I was to naive to put two and two together.

A short time later I heard the ops manager talking to someone about offering the people they planned to get rid of other work with the express intent of avoiding paying out unemployment.

I couldn't really do anything at that point other than warn my people, which I did. I found something else a short while later. I made sure to tell management why I was quitting, which was a long list of issues including them fucking over good people.
